#2 is a very good question . At first glance hubcentric seems to be a stronger method . The GM 2500 and 3500 SRW actually employ both , they are hubcentric and use cone lug nuts . The 3500DRW is hubcentric and uses swivel washer lug nuts . I think the real reason for this is the washer type lug nuts have a larger contact area to apply more clamping force which is where the true connection strength comes from , and need to be hubcentric to center the wheel . In order for the hubcentricity ( is that a real word ) to add to the strength it would have to be a press it , which it is not . It seems that hubcentric is more of a centering devise than anything else . Lug centric wheels take a little more care in mounting to make sure all the cone nuts are seated properly AND they have the correct taper . I'm still learning:)
Do you know the bore diameter of the OEM wheel?
I don't think you will find a mixed setup, if the lug nuts are conical it's lug centric. A tight wheel just helps with installation, but it probably a bigger gap than needed for hubcentric.
Dodge lug centric have a 1.7mm difference, which is small when you look at radius. DRW wheels on a Dodge have a 0.1mm difference, and that is what is needed to be hubcentric for centering and weight transferring purposes.
